#96 Editting a task freezes all other activity

[andré]

If one task is editted, one cannot view or edit another task.
However it would be very useful to be able to compare 2 tasks or directly transfer between 2 tasks, for example.
Since a task is opened in another window for editing, intuitively one expects that the main window would still be active, at least for tasks.

Version 0.2.10 on Mageia 5, 32-bit.
(Maybe really 0.2.12, since compiled same date that 0.2.12 released.)
