Performance problems when connected to GPRS

[Maverick]

The problem is present when I am connected to GPRS and additionally a voice call comes in.
In this moment my MDA(XDA) hasn´t enought performance to open the voice menue.
The procedure of opening the voice menue takes about 3 or 4 minutes.
I have heard that the source of the error are unused *.dll´s of windows CE in the RAM.

Does somebody know this error?
Is there a possibility to delete the dll´s automaticly?

Doesn't do on mine... But keep in mind, that if you use all 5 (or 4) timeslots, the phone is unable to start ringing but the network may signal the other side that it does (seen it in one buggy austrian network). Also, if you pick up the call, data have to be disconnected which usually takes a few seconds.

3 or 4 minutes are nonsense, the phone should not ring (I mean on network level) for more than a minute.
