Yeah, Chrome is meddlesome. Firefox takes whatever I throw at it, but Chrome sometimes has periodic issues. I actually load the keys slowly in order to decreases the chances of crashing in Chrome.
Nope, reasonable suggestion though. What OS and version of Chrome are you using? It's sporadic for me in OSX on Chrome 19.0. (Also, wtf is up with their ridiculously high versioning? The new browser wars seem to be based on version number.)
