In the good old VirtualDubMod, saving a screenshot of the currently displayed frame was so easy: Video » Snapshot source frame (Shift+1).
Trying the same in VDubFMod r38543 (32b) ... Video menu: No more matching entry. File menu: Export ... a submenu, that costs me precious time, unless there is a keyboard shortcut assigned; Single image ... no shortcut assigned yet, have to try to assign one later; click. Nothing happens?
Well, let's assign the shortcut. To File.SaveImage – seems valid. Test it ... nothing happens.
Let's try in VDubFMod r38544 (64b) ... pressing shortcut (was assigned for both versions, that's nice): OK, a dialog appears. Exporting a single image works. So it appears to be broken only in the 32b version.
Or is it? Trying again ... this time it works there as well?! Strange. A reliable bug could be found and fixed. But unreliable issues are the hardest.
