Blank Screen After Installing

Hi Chris, Thanks for replying. For some reason I cannot see how to reply to a forum post that has been replied to??!? Feelin like a newbie in more ways than one. OK, back to the issue: You are right, it wasn't a .tar. I was probably a .jar like you said and it did cause something to be downloaded. The Eqo app sits in the games&apps section of my phone. When I initialise it, the screen just goes blank and I have to cancel out of it to get back to the phone. Its just a blank screen. Note, out of the about 50 times ive tried it over the last 12 hours, just then when I cancelled out of it, or maybe suspended, I saw a brief flash of a yellow screen. Tried to repeat it but I can't. And when I "run in background" the java icon stays up for about 3-5 seconds before dissapearing. As for the JAVA setting on the phone: cldc v: 1.1 midp vers: 2.0 data space phone: 6500 free Heap Size: 1500 Im not near my mac at the moment but I remember that I didn't see any writing evident in relation to the icon in the dock of mac os-x. I can't remember whether I saw a mobile phone outline. I don't think I did unless it blends in well with the EQO icon. My eqo username is lenman74. Many Many Thanks I Can't wait to use this. Regards Len
