as per the title written an app which works perfectly on the simulator but freezes on the phone.

I'm using wait/notify to halt the UI when loading files and notify is being called when the UI should resume building itself.

been on this smae issue for weeks now(almost missed a flight because of it!) need to get it sorted.

Any ideas guys

just extra info:

it seams like it's waiting on a notify that never comes, but this should be the case across both shouldn't it. It hasn't crashed or anything like that because another thread that I have is still running and hitting breakpoints

[steff2632]

turns out its not the wait/notify, its the SQL access which takes much longer on device than with the simulator. I know the simulator is running on an i7 but thought that RIM had implemented some sort of virtulisation that would emulate the speed of the device.

Now my problem is speeding up SQL lookups for 500+ entries possible 20,000 apparently. Now using BufferedCursor 7 just placed index's into the database, anymore ways of speeding up database access? Using OS5.0.

Thanks in advance

use separate threads when running potentially blocking code.
