I've been on JB2 for about 2-3 weeks with only a few problems (mostly performance related) but in the past week I've seen a new problem which is intermittent, but once it happens it can only be fixed by a reboot, and even that doesn't always work (have to reboot several times). In short, the virtual keyboard doesn't put input into the text field. It registers my keypresses, pops up the magnified letter, vibrates if i have it enabled, but doesn't put it into the text field. If I'm in a field that allows the dictionary to be used then I get word suggestions as if the typing is working (but just not appearing), but the text isn't saved in the field. I installed the TickButtons keyboard before this problem began, and when I noticed the problem with the Android keyboard I tried switching but found that ThickButtons also didn't work. I wondered if installing ThickButtons might've caused the problem so I uninstalled it but the problem still occurred. I then reinstalled it (whilst writing this post because I couldn't remember 100% if problem occurred with TB also) and the act of installing the app fixed the problem temporarily (just like a reboot does). So, rebooting sometimes fixes it, installing an app (maybe just a keyboard one?) sometimes fixes it. WTF? Anyone got any idea about this? I'll upgrade to JC6 on the weekend sometime, and it should be gone, but it's baffling, disconcerting and annoying in the meantime.
