I'm having a few issues with 6.31RC4; I had been previously running 6.31RC2 (missed RC3 somewhere). When I go to launch it there is an extremely long delay before the app becomes "usable" (say 45-90 seconds at least). If I click anywhere it just says the application is not responding. If I wait it out, it wakes up and becomes usable (although if I want to see the MOTD it takes a while as well). When I double click on a file to download (like a file set, with PARs/RARs, etc), it puts the files into the download list, pauses all of the files except the first PAR, but then hangs and never starts.
System is a Core i7-2600k (but not OCd), 16GB Ram, Win 7 64bit. Like I said, RC2 was working fine as late as today for a minute or two before I installed RC4 over it.
Any ideas?
