DOS ain't dead

GVFM 2.66 beta /"Drive A" bug (Announce)

I've just uploaded Graphic Vision File Manager, version 2.66 beta 1 to here.

This is a full distro of GVFM, but only GVFM.EXE, README.TXT and WHATSNEW.TXT have changed from version 2.65. These changes are:

· Bug fix: PrevPathComp used "dec cx" followed by "loop @@LabelX". This might be the cause of DOS386's and Laaca's "Drive A" bug on FreeDOS.

· Optimised file icon type determination code. This makes scanning a folder much faster and may also be another cause of the "Drive A" bug, at least when GVFM is launched when the default DOS drive is drive A:.

· Minor changes made to README.TXT

As you can see from the above, I have found two potential causes of the "Drive A:" bug as described by DOS386 and also found by Laaca. Initially I suspected it was a[nother] FreeDOS bug, but I am now fairly sure it is GVFM after DOS386 said it still occurred even when he put his A: drive on GVFM's drive exclusion list.

This beta version has all run-time checks on, so it's a little larger, and will run a little slower than a release version. It will also generate a run-time-error at the slightest excuse.
