293	Inconsistent left mouse button behavior in all Qt apps with SNAP and animated pointers	Lewisr	Lewisr	"This one has been a thorn in my side for some time. I thought I opened a bug about it a while back. I'll look at this myself, as it's probably just a conflict, but this will document the issue in case anyone else sees it.

eCS 2.1
IBM Single Mouse driver 10.163 (TouchPad disabled in BIOS)
SNAP Build 505 (formerly saw this same behavior under SNAP Pro)
ThinkPad T43 / ATI X300 SXGA video (also on ThinkPad T43p / ATI X600 SXGA+ video)
Warp Overlay (possible issue?)
XWorkplace 1.0.9 (hook enabled)
Christian Langanke's Animated Mouse Pointer 1.01

        Conditioinal cascade sensitivity [x]
    Auto-hide mouse pointer not enabled
    Auto-move mouse pointer to dialog button enabled

Symptom:

Mouse hover works as expected. Middle and right buttons work as expected. Most of the time, however, selecting and activating anything with the left mouse button fails (the button press is registered on screen, but not passed to the underlying program). It is possible to hover the mouse to highlight a selection and then press <Enter> to activate it, or in the case of checkboxes or radio buttons, <Enter> or <Spacebar> will select.

It is possible to select a variety of checkboxes in a particular dialog (QPassGen is an example), and have none of them actually register in the application, though going back, deselecting, and then pressing <Spacebar> to select works.

Switch mouse pointer set to a non-animated set (default black, for example), and the left mouse button behaves as desired.

I do not see this exact symptom with Java applications, though the mouse can behave badly there, too (and when the memory corruption is experienced per http://trac.netlabs.org/java/ticket/65, I do see that the animated pointer reverts to the default black pointer. In all cases when that occurs, I know that INI files will not properly save and the system needs to be rebooted.

More on this as I narrow it down. It may be an issue with the Animated Pointer package, though Christian stated to me via email 2011-08-02:

    I am sorry to say that WPAMPTR has absolutely nothing to do with
    displaying the pointers! It only tells the system which one would to be
    used, and does that every some milliseconds. Therefore the only one to
    blame is the graphic driver, as this implements the interface that the
    system uses for displaying the pointer.

The last thing which might possibly impact timing and memory here is that I have Comet Cursor enabled."	defect	closed	minor	Qt Enhanced	QtGui	4.7.3	low	wontfix	mouse lmb select behavior
