Summary0015372: form designer component dragging fails
I'm running Lazarus beta (from fixes_0_9_28 branch in svn)
with FPC 2.4.0 (from release_2_4_0 tag in svn) under Ubuntu 9.10 with
the gtk2 widget set.

I run lazarus, and the default project comes up with a blank Form1, etc.

I drop a component, like a TButton or a TEdit onto the form. I click
on the component to select it. It selects correctly. I click and start
to drag the component to move it somewhere else on the form, and
rather than moving the component it just makes the dotted selection
box as if I've clicked on the form behind the component and i'm
dragging to select multiple items.

The end result is I'm only able to move components around my form by
clicking the component and doing ctrl+arrow keys or by manually
setting Top, Left, etc.

I've recorded a video of the phenomenon:

I reverted to the previous several revisions in that branch
(fixes_0_9_28) and found the following regarding this bug:

22886 - works fine, no dragging bug
22890 - lazarus fails to compile
22897+ - compiles, dragging bug is present

So this bug was either introduced in 22890 or 22897.
TagsNo tags attached.

Note that the bug doesn't repro in the trunk, it's a problem with something merged back into the 0.9.28 fixes branch, which is where it needs to be fixed.

I can confirm this bug. I'm using Ubuntu 8.04.3 and Lazarus with GTK2 widgetset.

Will this be fixed in the fixes_0_9_28 branch any time soon? I can't use trunk, but there are other fixes in this branch I do need. This bug makes completely unusable.
