Hello Andrey,
Thank you for your help.
This happens the same way for me every time I try to move a task, whether I use ctrl-M or right-click and "Move to". The "Move task" window always opens with View: "All tasks", and I can not change it.
In any of my Workspaces I can change the view normally, with Alt-V or by clicking on the view-name header. It is just in the "Move task" window that this does not work for me.
In the Move-task window, when I hover over the view name in the header, it changes color, then changes darker when I click on it. This appears the same as in a Workspace view. But when I click on the header in the Move window, the list of available views does not pop up the way it does in a Workspace view.
If I change either of the check-boxes for "Hierarchy" or "Hide completed tasks", then the view name changes to "*All tasks", with the star for modified view.
I am using MLO 4.2.0 on Windows-7/64 bit.
Let me know if there is more information that I can provide.
