Yesterday when working on GE I found some bugs, but they seemed pretty minor.
Saving your *.ged - When I saved my GED file to another location, it only saved 2 of the animations under the new data directory and nothing else.
Also, I had an animation which I updated the picture file then saved it and loaded it into GE. For some reason, when I re-saved the game, GE did not overwrite the old one, and did not save the new to the GE data directory. So, when I opened it back up later on, my old animation was still there.
Exporting bug? I opened a GED file from over the network(sometimes I save my GEDs on a different computer with a bigger hard drive). When I tried to export it, GE acted like it was exporting a game, but as soon as it was finished the icon for the exported game disappeared.
Also, I don't know if this is a bug, but when you try to load a font, it doesn't show the Windows UI, it shows the old GE UI.
I have GE 1.3.4, which is the newest version as far as I know.
