Error when updating Imagine plugin

[petermad]

If I update the Imagine plugin from for example v. 1.0.6 to 1.0.7 or downgrade from 1.0.8wip to 1.0.7 (or any other combination) and the old plugin is loaded (has been used) prior to the auto-install, then I get an error, if I after the installation try to view an image with Imagine.

I first get this error:

---------------------------
error
---------------------------
Crash in plugin Imagine.wlx:

External exception C000001D
---------------------------
OK Annuller
---------------------------

Or I get this error - whith varying addresses:

---------------------------
error
---------------------------
Crash in plugin Imagine.wlx:

Access violation at address 00000000. Read of address 00000000
---------------------------
OK Annuller
---------------------------

Wheter I get the first or the second message seem to depend on the version of the two Imagines I replace.

If I press OK, I can continue, but the image is not shown by plugin (any), but by IrfanView.

If I press Cancel I get this message:

---------------------------
Total Commander 7.55pb1
---------------------------
Cannot change Visible in OnShow or OnHide.

After restart of TC there are no problems.

I can reproduce this also in TC 7.04 and TC 7.50. And it happens with both ANSI and Unicode versions of Imagine.

If I run cm_UnloadPlugins just before auto-installing Imagine it doesn't happen, so it seems like TC doesn't unload the old Imagine properly before auto-installing the new one.

On the other hand - if I do the same with SGViewer (install a new version while the old version is still loaded), then it doesn't happen.

So maybe both TC and Imagine are to be blamed for this.

I have never seen this with other plugins, so it's probably an Imagine problem...
