[Q][PROBLEM] HTC Sense 3.0 Lockscreen issue - no 4 buttons
Hello All,
First of all - sorry for my english

Secound - I'm new in Android, my previous device was HTC Touch HD (aka Blackstone) - so I'm a little used to WinMo 6.5
I bought my Sensation last wednesday. It is a stock S-ON RL device (info about ROM is in my signature).
I have non-root'ed device.
Until yesterday (saturday) everything was O.K.
I set up a lockscreen with weather and one custom button (pointed to task manager - built one, not downloaded from Android Market).
Today morning i noticed issue with lockscreen.
There is no buttons above lock ring (any of them), and there is no weather shown.
I did soft-reset my device several times and that doesn't help.
When i go to "home screen" => "personalization" => "lockscreens" => and select
(screen 1a, 2a) any of them, then return to "Home Screen" and press POWER button (to activate lockscreen) and again POWER button to see actual lockscreen
(screen 3a) - I still don't see any of the four buttons (and weather)...
What's wrong? Anyone have ideas?

I don't see any setting, which could disable the four buttons....
If I wrote something ununderstandable, please let me know
Have I done something wrong? Why yesterday everything was OK? Could something be wrong during night? :/
Sorry for poor quality of screens, my work-phone is prehistorical :P
Any help would be appreciated

Thanx in advance
