From Bugzilla Helper: User-Agent: Mozilla/4.0 (compatible; MSIE 5.5; Windows 98) BuildID: 2001010901 "Twinview," Nvidia support for multiple monitors using a GeForce2 MX video card doesn't allow interactivity of a Mozilla window on my second monitor screen. This is seen in Mozilla 0.7 and Netscape 6.0 and 6.01. My graphics card is an Asus V7100 card and the second monitor is on the DVI connection and is an LCD screen. Any other programs I use work fine on the second monitor screen, including Netscape 4.7x. The Mozilla window, when move to the 2nd screen, has a functioning titlebar - as in I can grab it and move it, minimize, max. I cannot interact with the File / Edit menu, any buttons, or any links on webpages. The pointer remains a pointer, and doesn't turn into a hand when floating over links, and clicking on any element of the screen besides the titlebar yields no results. Reproducible: Always Steps to Reproduce: 1. On my system with TwinView capable card and 2 monitors, move any Mozilla window onto the 2nd monitor. Actual Results: Mozilla window is unresponsive to clicks, but can be moved back to first window and interacted with. Expected Results: Mozilla window should respond properly to user interaction, allowing clicking of hyperlinks, and access to File / Edit menus and buttons, URL window, etc. My system uses the NVidia GeForce Detonator 6.31 drivers, Twinview with 2nd monitor using DVI interface (IBM LCD panel). Video card is an Asus V7100/2V1D I'm randomly guessing that this problem would show up with any NVidia TwinView card and situation, but I'm not sure as I don't have another system like that to test.
This is some fun extra info: If I have the mozilla 0.7 window half on the primary monitor and half on the secondary monitor, I can interact with the half on the primary monitor, but not the half on the secondary monitor. Wild.
Seems to happen when monitor is in negative coordinate space. See bug 36550. Marking dup. *** This bug has been marked as a duplicate of 36550 ***
Good call on the dup. The "negative coordinate space" is right on target. I have my 2nd monitor to the left of the first / primary one, and the Mozilla window is unresponsive to the left.
