Martin, I haven't reported this bug because it's difficult to reproduce, but with some of the recent releases and many of the trunk check in there seems to be a lot of problems with the sparta docked form designer (DFD), at least on Linux gtk2.
What happens is that with the DFD installed on Linux gtk2 as the user tries to use the left mouse button in the designer to either click on or lasso select controls, the designer acts as if the previous selection is included in the selection. This happens randomly. The effect is that DFD is difficult to use. You go to select a control by clicking on it and instead it creates a selection group including the item you click on and whatever was last selected. This prevents users from editing a component or control using the DFD and instead they have to clear the selection (by clicking on a blank area of the form) then clicking on a control or component. It is very annoying, but doesn't happen 100% of the time, more like 50%. When you have a revision number you feel comfortable for me to test, I can try it and report the status of this issue back. If it fails with that revision I can submit a mantis issue and perhaps look at what's going on as well. For anyone else, if you are using Linux, gtk2, and the DFD, it would be helpful if you could confirm this behavior and perhaps note the pattern you see. That is what is happening when this problem occurs. Thanks.
