I have a big problem with it: sometimes (randomly it seems) I can't start it anymore (I click on it and nothing happens).

The only solution is to reinstall the application, very annoying. It already happened 2 times (reinstalled the app 3 times!).

A reboot doesn't help.
What could it be? Thanks

It happens with Java applications. First, check if it has a new version. After that, make sure that you have enough free RAM memory to Run a Java application (I assume that you use an N81, because N82 have a great memory).

I have an N82, I forgot to mention it, so it is not a RAM related problem, I suppose (I have ~88MB free ram when I try to run it).

However I reinstalled it (same version, since I already reinstalled it a couple weeks ago) and now it seems to work, but I know it'll happen again...

No other java application has this problem, only gmail (the most important one..).
I want a native s60 gmail :/
