VS 12 extremely slow when library full of clips

[hanspeter]

Hi

I am desperate, opening a new thread in hope for help (I know one should not do that....but I fear that nobody will respond any longer to my other thread).

My VS12 on Windows 7/64 machine with 4G RAM has slowed down dramatically when I have lots of clips in the libraries. I have several libraries based on themes, each with about 10-20 clips of 10-20sec duration (PAL MPEG2 clips, no HD). Loading into the libraries from the external USB2 hard drive is extremely slow. With each clip to load VS12 gets stuck for a while and until all clips are loaded it takes a long time) And when you want to move the scroll bar in the library it does not move, you have to click several times and the mouse just shows the blue ring for a long time and you get Windows to react that VS12 does not respond. When I try to enter a new library it will only show after I click "Close" several times and with a long wait.

When I delete most of the libraries VS12 runs a bit quicker.

All other programs (for instance Firefox and mail) run well and with normal speed (normally I have them closed when using VS12). So it clearly seems to be in VS12.
I used VS12 the last time in June to edit a video and at that time it worked well, with normal user friendly speed. Since then I only updated all Windows, Adobe, Quicktime and other important program updates, but nothing else. Also Direct X is updated to the latest version Microsoft issued in June 2010.

I experience the same situation both on my Windows 7 and Windows XP machine (XP having less process power and less RAM, only 2G, but worked perfectly before). Somehow the impression is that the latest Microsoft NET Framework patch could have caused this, but I am not sure and I would not like to deinstall this patch because of the security risks.

My question now: has anybody experienced the same thing? And if yes, what has been the solution for it.

Hope really for help because I need to edit a new video urgently. Thanks.

I can understand your concern but the other post was replied to on 6th by Ken with your reply on the 7th, I am sure he will reply given time.

So as not to cause confusion with duplicate posts I have taken the decision to lock this post.
