Summary0001948: Hangs after wake-up from sleep
DescriptionApp works great until PC goes to sleep. Upon wake-up Speedfan UI locks up with status/log window repeating "Waiting SMBus IDLE..."

At this point the GUI is frozen and fans won't speed back up, causing PC to overheat. If the app is killed from task manager and then restarted it can then talk to the SMBus without problems, but the configuration is completely messed-up and has to be recreated.



Steps To ReproduceGet setup properly.
Start SF normally.
Put PC to sleep.
Upon wake-up SF is locked up.
All other apps are fine.
Additional InformationNormal startup log:

My guess is that the video card communication stops working. Please, contact me by email (alfredo [at] almico.com) so that we can further investigate.
