Dropping out connections, etc., and general pain was the normal state of PC-syncing for this particular phone (probably exacerbated by my history with Windows Mobile perfection!) — so today I snapped and went looking for a software update.
There is one. It is so near perfection it makes me cry.
If you’ve been let down by older versions of SE’s PC Suite software, give this version (2.10.38 at time of writing, I was upgrading from I think 1.17.x?) a try. 44MB download, but well worth it.

my phone is not opening its application and games what can i do.
The PC suite takes control every 2nd second and I lose focus in hte program I am working in!
This is a problem we all have here and makes Sony Erocsson PC suite complete useless!
And yes, I have version 6
The problem seems to be related to lack of connection to a phone. When there is a phone connected, the problem seems to cease
