Unfortunately the error isn't in my own code, it's in the compiler library, in the code when closing a window.
1. What were you trying to view?
2. Any Lister plugins installed?
3. Is this within the virtual machine?

[MaxX]

1. Just a regular ansi text files with some personal reminders for me to do. No media or archives are affected, I can F3 on them without errors.
2. I have two WLX plugins there (Imagine Unicode and Total7zip). But I also tested that with empty [ListerPlugins] part and have the same result.
3. Yes, it is guest machine in VirtualBox, just as I wrote in the topic. Any local files on C: (vhd) or D: (optical) of guest machine are shown fine. That only affects regular txt files on Z: (shared folder).

UPD.
Seems I found the possible reason. Just noticed that TC with empty ini does not fail in the same conditions. Then I tried to delete some wincmd.ini parts one by one. And stopped on this one:
UnwrapWidth=16384
Error is gone without it. I have added it few days ago. Is there any limit in XP for it?

I tested UnwrapWidth=16384 on Windows XP 32bit (regular installation, not virtual), and could not reproduce the problem.

[ghisler(Author)]

It could be the VirtualBox display driver: Some drivers seem to have a limit of 8192 characters in the DrawText/TextOut functions and crash when passing a longer line to them. Can you try with UnwrapWidth=8192 or UnwrapWidth=8191 instead of 16384?

[MaxX]

I've checked this deeper.
Max working is:

Code: Select all

[Lister]
UnwrapWidth=7679

and anything less.
Value of 7680 (and any bigger) causes the reported error.
