It's strange. Neither can I find it in wincmd.ini section of the help file (I've quoted what Help says in previous post), nor can I serch it out, there's no "PreloadThumbnails" item in "search" tab at all.icfu wrote:@Raymond:
The value IS MENTIONED in wincmd.ini section of the help file. Switch to "search" tab after calling help and enter "PreloadThumbnails" there...
Looks like we are using different verions of TC, at least different Help files.

In case there're something wrong, I just dowanded TC6.5 again from official website and checked it out. Nothing new.
Could you please paste here what "your" Help says about "PreloadThumbnails"?
