Version Evo 2012.3.5 Locking up 
Autore: Frank J.Hi
I have just updated from X5 Evolution 16.3.1 to X5 Evo 2021.3.5 and after a day or so of working OK, the latest version keeps locking up, or rather it spend much time with the wheel spinning.
I have left it for up to an hour with no result.
When I open the software and load my site I can navigate around the map with no problem but if I try to add something, say, an image or text, that's when the lock starts.
Running Task Master during lock up tells me that X5 Evo shows Power usage to be Very high.
If I run the previous version X5 Evolution 16.3.1 with exactly the same site material it all works fine. Task Manager shows Power usage to be Very low.
To recap, initially, the new version worked OK. Then the lock up was short and only occured when I did a Preview. Lock ups increased until now whenever I try to make a change it locks.
As it stands the updated version is unusable and I might have to revert to the old, and consider the update fee a waste of money.
I am hoping that someone will have a solution for this problem.
Thanks in advance
Frank
If you have empty fields in the pages (with 4 pages - create pages), you should fill them up with HTML code objects, these can remain empty. This reduces the computer load.
Very large projects with many PDF files and large images can also use up the computer.
How big is your project?

If we observe this and the computer and the Windows operating system are up to date, there should be no long waiting times.
Exactly as JJ said!!
You almost certainly have empty cells on pages. This was seldom an issue in v16, but it is an annoying "feature" in current versions. Like JJ said, fill every cell, row or column on every page (I simply add a text object but I do not add content). As you edit pages it is a simply matter to use, change or delete unnecessary objects.

Hi JJ and Esahc
Many thanks for that. I have now eliminated all the empty cells and it all seems to be OK now (time will tell, perhaps).
A I have a lot of pages and was rather profligate with empty cells, that was obviously my downfall.
Yes, it seems that newer versions have 'introduced' this problem as my earlier version was happy with all these empty cells.
Thanks again
