Hello Daniel,
I have found the error:
Guide 7.2.10 (Lenovo T550): Please take a large project, modify something and save it. Saving will take a few seconds.
While computer is saving the project press "E" and go inside one page and to the next and so on.
If you do this fast enough, your pc will hang up!
Guide 7.2.9 on other laptop, lenovo L540,: It doesn't hang up by working while file is being saved.
Then I have installed 7.2.10 on Lenove L540: The same effect: By klicking through pages and while pc is saving project, pc hang up!
I think, you have to block working, while pc is saving a project! Now I wait a few seconds till saving is finished.
If you can not simulate this bug, please let me know and I will send you a very large file to helpdesk.
Perhaps another Guide users can test this: Saving a large project and going inside pages "E" very fast.
By working with Plus+1, I press very often the "Save Button" and go on working directly.......
Bye
P.S.: In windows task manager I have watched: Guide needs 76 seconds to save my project (DP610: 30% ROM-, 15%RAM, 41%NV- memory used) !
