Hello Bernt,

This is not acceptable indeed. To see if the issue is related to a 
memory leak, you can try to use Task Manager or Resource Monitor to see 
whether the memory use of LyX grows, and whether it grows enough to 
trigger swapping.

But if memory is not tight, a memory leak does not in itself cost 
performance. Therefore, there may be other issues at stake. However, 
"working for a few hours" is not something that I can reproduce easily. 
(especially if we do not do the same actions).

@Windows_experts: are there tools that could be used to profile a work 
session (and that are not too annoying performance-wise)? What kind of 
data do they require? A version of LyX with debug information?
