Running Fences 4.0.7.2 on up-to-date Windows 11 Pro 21H2 build 22000.978. Periodically - like once every couple of days - all the fences on my desktop start flickering at a rate of about once per second, and when that happens I get no response from trying to start any of the programs in any of the fences. While this problem is happening, I can still start the same programs from the start menu without any problem, and any running programs I have continue to run normally, so the problem appears to be only with Fences. Usually, after a minute or two the flickering stops, and the fences then go back to behaving normally.
Any suggestions on why, and/or a fix?
