Whilst I try to upload a file via sendit and Firefox 3.5 the screen freezes every time. Also the same process with IE 8.0 (64bit) brought the same result. Very frustrating. And recently my screen has frozen randomly whilst browsing the net. I read here before of same problems , but I have found no answer still yet. Im running the RC (64bit) and thought of buying a regular version, but if there will be the same bug still alive, Win 7 will be not my candidate. In XP I had never such problems.

Please upload a file to Skydrive (www.skydrive.live.com) instead for a test. Does the browser still freeze up? If the file can be uploaded fine, you may need contact Sendit support for further assistance.Usually, this kind of issue can be caused by incorrect browser settings, incompatible third party program or virus. Here are some suggestions you can try.1. Reload IE settings and upload a smaller file via IE8 again.2. Perform a Clean Boot for a test.3. If the computer connects Internet via router or wireless network, please bypass it and connect to DSL modem via wired cable. Then, please upload file in this mode.Thanks,Novak

In meantime I have had success. 1. I cant believe that an error on yousendits page causes a freezing desktop on my computer? 2. Freezing desktops are always to count with whilst browsing (at least to me). 3. What me wonder is the randomly appearance. 4. If there might be errors on third parties, what is it a kind of error handling that causes freezing desktops? However, thx a lot for taking time and answering, Horst Schmier.

perhaps uninstalling Firefox would help. There are known vulnerablities and issues. Firefox alert here.

As Nano said, please uninstall Firefox program for a test. Meanwhile, please also perform a Clean Boot and then check whether the Desktop freezes up or not.

Thank you all so much. Ill give a clean installation a chance. Horst Schmier
