If left running in background for certain amount of time then omniweb crashes
 

Problem im having is that if i leave omniweb open in the background without a window open, but so that if i require the internet quickly i can just click on the dock icon, after a certain amount of time, if i click on the dock icon to open a new browser window then omniweb freezes and i am forced to force quit the application and then restart it. This seems to happen 95% of times if i leave the program unused in the background for more than 10 mins. It is SO frustrating and has infact led me to switch to an alternative browser for now. Any ideas?
