Crashing Verb search.

Crashing

I have found Logos to be a very helpful tool, however 1 out of 3 times I use logos it crashes. I have found that opening up resources from the + tab will cause it to crash every second time I use this. But the lastest frustration is using the vocab search for some reason i can search for nouns without it crashing but as soon as i search for verbs it crashes every time. is there something that i need to do to stop this? I am pretty sure that my computer more than meets the requirements using a Mac, 8 gig ram, 2.6 Ghz 2 Duo, Lion 10.7.2
