selection bug

In the following structure, double-clicking on some of the Ph groups highlights the whole structure (correctly), but double-clicking on other Ph groups highlights only that Ph group (incorrectly).

Dear Bob,

Sorry, but I couldn't reproduce this bug neither in 6.2.1 nor 6.3.0. Can I ask which version you use?

Regards,
István 

I'm using 6.2.1. I've since found that the bug is very subtle, depending on exactly where the mouse is pointing when I double-click. Or maybe it depends on how fast I double-click. Anyway, it's not extremely reproducible, but it's there.

Dear Bob,

You are right, the selection depends on the pointer's position and the speed of the double click. I don't really know what can we do to make it more convenient, but i have created a ticket in our issue tracking system.

Regards,
István
