Facebook mobile site...problems?

I'm more fond of the FB mobile site than the stock fb app, but many times when i go to comment or post something i can type it up, but when i hit "post" or "comment" to enter it, it doesn't work, like the browser won't run it. it seems most other sites work fine, one time i had a heck of a time getting any site to load.

if i shut the phone off and turn it back on it seems to let me comment or post things...is it the site, or am i having browser issues? i'm having other issues like sms force closing from time to time and a couple other little things, i don't want to exchange my phone for no real reason if i don't have to.

so...is it the fb site or my browser?
