Hi I'm having the same exact problem with FlashFXP constantly crashing. It just closes, I don't receive any error messages or anything and it's when I attempt to It seems to be since I installed Vista SP1. I don't get a virus reported, but my Firewall/Virus protection is Microsoft OneCare (tried disabling firewall, no luck).
I just found something interesting, it doesn't seem to have anything to do with the actual file transfer, because I can make it crash by sending OR queuing up a file (whether I'm connected to a server or not).
I just found something else interesting. It happens on any file from my desktop, but not on any file from my Documents folder. Now that I think about it, I have my UAC stuff disabled so I never get prompted, it should just automatically allow it to proceed. Could this be the cause? Could you guys try disabling the UAC prompts in Vista and see if you can reproduce it?
Please let me know if there's any other information you would like me to provide.
Specs:
OS: Windows Vista Business (Service Pack 1)
Memory: 2GB
FlashFXP Version: 3.6.0 (build 1240)
Thanks
