I bought a Tungsten T5 recently and found that I had one of the models which was prone to crashing so had to update it, which I did successfully. After that I added some 3rd party software (Date Bk5, BP Mgr, London Tube etc). It was then that I started having problems with crashing, and the bottom third of screen staying completely blank. I did a hard reset after removing all third party software and all is fine except for a 1-2 second blank shimmering screen every time I use the home button (quick or on screen), or use the other quick buttons following home button. I would take it back to the store but I bought it in another country which makes it difficult. I am new to Palm handhelds so would be grateful for any advise. Thanks.
