This was the reply I got from Pete Dowson (FSUIPC), it should be very useful if Support reads it:

Known? strange, then, that no one has written to me about it. If this aircraft uses FSUIPC and has run into a problem with later versions, someone should talk to me about it. There is no way I'm ever going to be able to buy and test all add-ons for FS for every new release of FSUIPC!

Did the person who determined this ever state why?

""... and in the forums, the recomandation is to go back to version 4.3.- I made some trials, and noticed that the most recent version free of the problem is 4.323, in newer versions I found the problem. Is there a workaround ?"

It sounds like a possible bug in the Captain Sim add-on: maybe they are not clearing the flag they must be setting in FSUIPC which tells it to disconnect controls. FSUIPC has a 10-12 second timeout on updates to that flag in case of bad or hung apps. If this is all it is I'm sure it is something they can fix quickly enough.
I'm not aware of any difference between version 4.323 and later versions which would change these things, though, unless it worked by fluke before because of some older FSUIPC bug now fixed. I really would need more information to help. Why has no one who knows what they are talking about contacted me?

Regards
