EQO Software Problems with Sony Ericsson K800i

Dear EQO Team,im a Big Fan of your Mobile Service and i really enjoy your nice Service every Day.But i've discovered a Problem with using the Software (Version 1.6.1) on my Sony Ericsson K800i that i've already reported to your Support by E-Mail,but i havent got a Answer from you since today...My Problem is this: When i start the EQO Software on my Phone,everything works well,the Login,the Connection,everything just fine.But when i use the Instant Messenger Service in your Software to Chat with my Friends,the Software gets really slow with just every Action after a few Minutes.That means i cant write my Messages in the usual Speed and have Big Problems to control the Software correctly...after shutting down the Application and restart it again,everything works well again but after a few Minutes the Problem is there again.I've tried many Ways to fix that Problem by myself,I've deleted the Software from my Phone completely and downloaded it again,but the Problem is still there...maybe you could fix that Problem with a new Software Update or something like this,its just a lil Bit sad for me,because this Problem forces me to use other Instant Messengers on my Phone which runs without Problems but i really would like to use YOUR Service...Greetings from Germany and keep up that great Work! :-)
