GIMP portable works okay for editing images already saved as standard image files on my computer.
I am running Windows XP Professional and I have two different (Microtek and Hewlett-Packard) flatbed scanners I use at different times to acquire document images.
When I try to use the 'File-Acquire-TWAIN' function to acquire images with either scanner connected and turned on, a small window titled 'Select Source (Not Responding)' appears and GIMP locks up.
When I select the red 'X' in the upper right corner of the small window, an error message appears:
----------------------
GIMP Message
Plug-In crashed: "twain.exe"
(D:\GIMPPortable\App\gimp\lib\gimp\2.0\plug-ins\twain.exe)
The dying Plug-In may have messed up GIMP's internal state.
You may want to save your images and restart GIMP to be on the safe side.
OK
-----------------------
I can acquire images directly from any scanner I own using the TWAIN acquire functions from other image manipulation software programs such as Photoshop without problem.
I would like to avoid a separate operation to scan and save images from a scanner using other software before editing those saved images with GIMP.
