Can't interrupt thumbnailing on network share drive

[JohnFredC]

Sometimes I forget that a tab is in thumbnail mode and navigate to a (relatively slow) network share that has lots of image folders.

TC dutifully starts thumbnailing the new image folders, but the UI freezes until thumbnailing completes. If I switch away from TC, I cannot redisplay its window until the thumbnailing completes. TC appears in the XP task bar but reports "Not responding". If I wait long enough, TC completes the thumbnails and reappears of its own accord.

Very frustrating. The TC menu does not "blank out" as it does when TC is waiting on a network share, so, until I switch away from TC, the TC window looks normal, the thumbnails appear gradually as they should, but TC is completely unresponsive.

Today it was 5 minutes before TC completed the thumbnailing and returned control to me. I could have stopped it by forcing TC to close, but I thought... might as well generate the thumbnails.

I'm not always able to be so sanguine about it.

Strange, thumbnailing is done in a background thread! You should be able to click on a different tab or switch to a different directory while it is active.

Usually I can...

This situation involves a slow network share (connection slow, networked drive also slow) and hundreds of large jpgs in many subfolders. That's a lot of network traffic as well as a lot of processing and file access on both sides of the connection... apparently some part of that chain doesn't want to give the TC GUI any cycles.
