... every couple of days I find that I need to restart my phone to persuade my virtual keyboard to open again ... it just seems to stop responding to me tapping in text boxes for some obscure reason ...

My virtual keyboard doesn't work any more . I restart the phone 3 times but that do nothing

turn of the virtual keyboard in the settings restart then turn on again. worked for me

mine still doesn't work have turned it off and restarted, I also reflashed the phone with the new FW, It still comes up as a blank keyboard?

My N900 virtual keyboard is not poping up at all.

I already tried restarting the phone several times, changing various settings on both "Text Input" and "Language & Region", but nothing solved the problem.

I am not sure if it stopped working after flashing the device to PR1.1 or after installing some apps, but I guess the last is the most likely.

Does anyone know about a related bug or conflicting app?

Just got it working again... but there was no change at all...

It seems like an intermittent bug, the kind of it is hard to find the cause. I've read other threads that mentioned a lot of different apps conflicts that could be causing problems with V.K., so I guess it is an O.S. bug.

Its a very easy problem to take care of.I've sent the solution in another thread but i'll send it here too,afterall nothing's fun enough without sharing it with others..Ok now,Here it is,I'll go through it step-wise..
1: Open application manager and go to uninstall
2: Uninstall MSCIM or SCIM that you have
3: Open X-Terminal
4: sudo gainroot
5: cd /etc/event.d(There's a space after 'cd')
6: ls
7: After 'ls',see if 'scim' is there in that list that comes up,if its there just remove it with the following command.I'll just write it as '8'
8: rm scim
Now type '9' and '10' exactly as i do,
9: /usr/bin/gtk-query-immodules-2.0
10: /etc/gtk-2.0/gtk.immodules
Even if '10' doesnt work,taking care of step '1' to '9' should make the virtual keyboard work.Let me know how it went..
