TC looks for the gdiplus dll first in the System directory (GetSystemDirectory), then in the Windows directory (GetWindowsDirectory).
Well, I don't have a gdiplus.dll in neither the system directory nor the windows directory only in the windows\winsxs directory on both my Windows XP and my Windows 7 x64 computers - yet gdi+ works exept for this bug under Windows XP.
On my Windows 7 computer I have noticed that some programs have their own gdiplus.dll in their program folder under "c:\Program Files (x86)".
Maybe TC should be shipped with it's own gdiplus.dll too.
I have noticed that I don't have to use F2 to view the image with gdi+ under Win XP 32. If I move any window in front of lister and then refocus lister then the part of the image that was covered by the window is now shown.
If I have image viewing plugins installed in ny TC and I press 4 to switch from the plugin viewer to Lister's internal viewer the image is shown immediately.
If I load the image in a separate Lister by using %COMMANDER_EXE% /S=L:P path\83120.jpg then the image is also shown immediately.
