Sorry I didn't see this post earlier.

There are quite a few bugs in FE, and one can be what you describe, But a lot depends on the FE version, and which Windows version you are running. The multiple open windows problem isn't uncommon. It seems to be related to the amount of RAM you have. It uses a lot of memory. This is more pronounced in the later Windows versions: XP and later, and could also be exacerbated by RAM load from virus checkers and other apps. Increasing the pagefile allocation can help a bit, but hardware RAM increase helps more. (to increase pagefile allocation: Start; System; Advanced). Processor speed may or may not to be a factor.

One fix that I know about and have used, is something that doesn't seem to make sense. If FE stops working properly, n any of a number of ways,  including freezing up, you can fix it by deleting the FE folder altogether and then reinstalling everything. Simply make a new folder and unzip everything into it, including the landcape libraries and compiler. I'm a beta tester from way back, and nobody was able to work out just why this happened. But I do know it works.

As far as I know there will be no new versions of FE. The Ukranian authors of the programme have disappeared. The source file is around. I know at least one person who has it.

Well, I hope this is helpful. Good luck.
