Coherence mode doesn't work when multiple users are using Parallels

[FelixII]

Hi,

I'm running Parallels 8.0.18494 on OS X 10.8 and have a problem with coherence mode when working with multiple user accounts. Only the first user who starts Parallels can access coherence mode. I can reproduce the problem on my iMac (Late 2012) and my MacBook Air (Mid 2012) by performing the following steps:

• Quit Parallels Desktop
• Log into another user account and start Parallels Desktop (you don't have to start a VM)
• Log back into your normal user account and start a Windows VM (I tried Win7 and Win8)
• Open a Windows program and enable coherence mode
• The program appears in the dock but you can't access it. In mission control the program label appears, but the program itself is invisible

When I hover above the program in mission control, it looks like this:

My parallels.log file also contains some errors when the bug occurs:

Can anyone reproduce this issue?

Thank you for your help!

Hi,

the problem still occurs for me with the latest Parallels version 8.0.18608. Can anyone reproduce this issue?

I had this issue and went back to version 7. I had to upgrade to version 9 for Mavericks and now I have the same problem as before. Only on users account can be in coherence mode.

Same here. I'm using Parallels Desktop 9 + Mavericks.



Recently, I added user account for my wife. Coherence mode is not working after that. The window from guest OS is invisible.

Can't I use coherence mode with multiple user account?
