When I move the mouse cursor from the code editor panel to the Project explorer panel and select some file on second, the file drag&drop action occurs. (One toolbar group were jumping to the fist line from the second line) Reproducible: Sometimes Steps to Reproduce: 1. Show many buttons in the eclipse toolbar. Some buttons must be on the second line. 2. Do mouse click on the code editor panel. 3. Move the mouse cursor to the project explorer panel, and click on a file. 4.

Interesting, so the movement of the Project Explorer is causing the start of a drag it seems. To SWT for comments.
Notice that when the user clicks on the editor one new toolbar is added (one with two items), this new item causes the last item to wrap to a new row. When the user click in the package explorer that new items is removed, and the toolbar is relayouted back to one row. This cause the tree item under the mouse to change. Because of all this dance a drag start is being (wrongly) initialized. I suspect UI has its own code to detect drag start, and that is where the problem is. I'll try to prove my theory tomorrow if possible.
This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet. If you have further information on the current state of the bug, please add it. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant.
