On a Vista system, I had been using dial-up with TI 11.8053 until 11 May 2009. On 11 May, I switched to cable internet. A bit earlier this evening, I replaced TI11.8053 with TI1.8101. As we speak TI is in the verify phase of an image backup. For quite some, actually until less than a minute ago, I could not access the files on the network drives. Why would TI lock things up during a Verify? I could, if in one of my rare good moods, accept such a lock out during the backup phase. Any ideas? P,S. I do not believe that I ever tried to access network files when TI11.8053 was installed, so I do not know whether 8053 had the same issue.
