Hi all, I'm having a wierd mouse click bug with recent versions of FSO. I'm currently using the 20040405 build.

When I'm in the weapon loadout screen, clicking on the guns or missiles sometimes fails to select the weapon. I have to either keep pressing several times before it is finally selected or I have to press the "scroll up and down" buttons before the weapon is finally selected.

And once this problem starts, it spreads to the briefing window as well, and I have to click a random number of times on a briefing room icon to reveal its type.

This problem doesn't occur with the main menu or options menu, only in the weapon loadout/briefing and sometimes ship selection screens.

I have no mods or other modifications except the media vp installed.

Machine Specs:
AMD 1800+
512MB RAM
GeForce 4 Ti 4200
SB Live 5.1

Any ideas on how to fix this problem?

optical/wireless mouse?

I'm using a wired balled PS/2 mouse.

It only happens in FSO and only in the loadout screen. It works fine in FS2 and the older builds of FSO.

This is just wierd...

I've had this. I just ignore it...

Then again, I had it in retail FS2 so...

i also have this, but only in recent builds of FSSCP.  I have an optical wireless mouse.  Not sure why that matters even... doesn't FSSCP use directInput?

I've had this before with the Linux version (icculus.org).  Some builds of FS1 would do it and builds of FS2 with the same code wouldn't.  I tried diagnosing it a few times and it looked like the mouse button press was getting reset before the frame was done and it never got back to the menu doing to check.  Usually on the ship select screen it would detect the down press but not the up so it would just drag a ship icon around the screen.  At one time I had a freaky little hack using snazzyui to detect a mouse press but it couldn't be used everywhere and I think I just gave up.  Linux uses SDL for input so if it happens with DirectInput as well then it's something generic in the code that's causing the problem.

Ive had it with two or three FSO builds - that was quite a while ago though and didnt happen with any build since 11-18-03

After some further testing, I realised that this bug only occurs for me in Direct3D8. It works fine when I run it in OpenGL.

I recently reinstalled Windows and found out that this bug no long exists. After fooling around a bit, I discovered a possible fix for those who have this problem.

If you are using a Refresh Rate Override tool, try turning that off first and use the application default's refresh rate. It solved the problem for me in D3D.

I have this problem now and again, it comes and goes, it's weird

I've recently started having this problem.

I had a problem similar to this a while back, though it was with everything on my computer.

It turned out it was the mouse. The plastic stuff inside had worn down so that it would only work when I press a certain way.

Ditto, except I have a wired optical mouse. It IS very annoying.

To everyone who's been having problems, try turning on V-sync...that's what was causing it on my system.
