My Citrix published applications seem to be stuck to a monitor and are not moving or maximizing correctly.

The first thing to check will be to ensure that your session memory is adequate for your screen resolution and number of monitors. The steps for ensuring this are listed at http://www.splitview.com/node/65

This can also happen if the default.ica file has an incompatible setting.

In the default.ica file (which is usually located at x:\Inetpub\wwwroot\Citrix\CitrixAAC\conf\default.ica for web interface –and– x:\Inetpub\wwwroot\Citrix\PNAgent\conf\default.ica for PN Agent), check if the following line is present:
[Application]
DisableMMMaximizeSupport=TRUE

When this variable is set to TRUE it causes these issues: Windows are maximized to the left most screen, the arrows will not allow the seamless window to move left or right and if you resize the window, move it to the right screen and maximize it, it only takes up a small sliver of the screen.

The fix is to set:
[Application]
DisableMMMaximizeSupport=FALSE

This must be done at all Citrix login points.
