I haven't experienced crop box problems to the extent you have but Vuescan
has always been difficult to set the crop lines in, though there has been
some improvement over the last several months. Ed's up to version 7.0.27 so
you might try that.
As to the memory hang-up, I guess is the software - it must retain the
memorized image in whole or in part even after closing down. You might try
clicking "file - release memory" before closing to see if that helps. I
picked up some freeware called Ramboost which frees up unused RAM and closes
unused DLLs and it seems to do a good job - I put it in my tray and just
click it when needed.
but there are many others like
it.

Subject: filmscanners: Vuescan crop box goes mad. Film at 11
| I have no idea why, but Vuescan's crop box has gone loopy on me. I'm
using
| 7.0.21. I've been attempting to scan some frames of 35mm colour neg film
| using the motorised film strip adapter in my Nikon LS30. I've been using
| the zoom function in Vuescan to adjust the edges to include the maximum
| amount of the image without going over the edge of it. For the first
couple
| of strips of film, this was fine, but the crop box now won't behave at
all.
| Here's a summary of what it's doing;
|
| 1) If I click in the middle of the crop box and try to drag the box, the
top
| edge of the crop box jumps down to where the cursor is and tries to drag
the
| top of the box. Before clicking, the cursor looks like a hand. After, it
| looks like a corner drag arrow.
|
| 2) If I try to drag the left edge of the crop box, pointing at the edge
| changes the cursor to a left-right arrow, but clicking and dragging makes
| the top of the crop box jump down again as above.
|
| 3) If I try to drag the bottom edge up, the top jumps down again as above.
|
| 4) If I try to drag the right hand edge, same thing.
|
| 5) At one point I was able to drag the top edge up, but every time I went
| back to the preview tab, the top edge bounced back down a couple of mm.
| This lost me about the top 1/5 of the image.
|
| As a result, I can't use the mouse to set the crop box at all. Thinking
| something may have gone screwy in the INI file, I deleted it, and
| soft-rebooted the computer to ensure there was no previous remnant of the
| program in memory. The behaviour hasn't changed. I've managed to get the
| crop box maximised by manually adjusting the measurements in mm in the
crop
| tab, then looking back at the preview tab. This was initially confusing
| because with a normal landscape image, the "x" and "y" values are
reversed -
| ie. x is the vertical measurement on the screen and y is the horizontal.
To
| Vuescan, a portrait layout is "no" rotation, so most photos require left
or
| right rotation, and afterward the relationship of x and y gets confusing.
| Part of the problem seemed to be caused by large xy offsets. I had to
| experiment with reducing the offsets before I could get the crop box
right.
| I'm not sure how consistently the offset values behave - with the image
| rotated to the right, the offsets seem to be from the top and right edges
so
| in portrait they would be from the left (x) and top (y)?
|
| Zooming doesn't seem to help. Also I've noticed that when zoomed it
doesn't
| seem to be possible to see the bottom edge of the crop area. The bottom
| edge of the crop box can't be seen with a full 35mm frame zoomed.
|
| One small unrelated suggestion for vuescan; I would personally find it
handy
| if the final output display (the "scan" tab) was shown immediately
*before*
| writing the crop to disk. As it is, I have to sit around for ages before
I
| get to see what the final crop actually looks like, instead I'm looking at
| the previous scan.
|
| Has anyone else experienced this strange behaviour of the crop box, or is
it
| only me? Does anyone have any idea how to stop it?

|
| PS Another misbehaviour of my PC *seems* to be related to Vuescan. After
| using Vuescan and closing it, an amount of about 20MB of RAM doesn't seem
to
| be freed. More importantly, Win98SE won't shut down and switch the
computer
| off. Instead it hangs at the "Your computer is shutting down" splash
| screen. On reboot (requiring power off or hard reset) the computer
| bluescreens with a 0E error just at the point where the desktop comes up.
| Hitting enter to close the program (god knows *which*), the dekstop comes
up
| OK. If I restart (using shutdown/restart) at this point, the computer
| restarts normally without the bluescreen. If I shutdown instead, it shuts
| down and switches off. I was wondering what was triggering the bluescreen
| as it seemed random, but I'm now convinced it's something about Vuescan's
| use of memory.
