Every now and then in what appears to be a completely random occurrence (about 1 in every 20 views) my thumbnails are blank. The frames are there, the dark-gray background is there, you can click on them and they take you to the correct page but the actual thumbnail image is missing - exactly like setting PauseThumbsLoading = True except my code looks like this:
tn.PauseThumbsLoading = False
Dim myStatus As GdPictureStatus = tn.LoadFromGdViewer(gdView)
There is NEVER any error condition raised. myStatus ALWAYS = GdPictureStatus.Ok
Has anyone else seen this kind of behavior and is it possible there's another property (properties???) that are having a similar effect as PauseThumbsLoading that I should be setting?
Any advice would be very much appreciated!

Thumbnails are Blank
Re: Thumbnails are Blank
Hello Curtis,
It will be hard to reproduce the case.
Here some solutions you can try:
- If your file have a lot of pages, use the property PreloadAllItems and set it at false, it will load only visible items.

- You can also test if you thumbail image is well loaded bu using the OnAllItemsLoaded event, and use the method ReloadThumbnails if not.

Tell me if it works!
