Altium 15 PCB tool panel freezes

[stark_10]

Good night to everyone.  I just installed Altium 15.  It works like a charm... except for every PCB tool, like the PCB library.  the panel where the grid is supposed to be shown is frozen.  It just shows whatever was there, like when a Windows application is not responding.  I can´t drop a pad, more likely I can't see it.  However, the HUD display with the coordinates do show.  Not other tool, like the schematics is affected. I was wondering if someone could please tell me how to solve this.  It is an old PC that was just taken back from retirement (Pentium 4 HT), but it has a Quadro Graphics chip.  I could run Altium 10 without any problem, or much more graphics intensive software like CATIA or SolidWORKS.  Thanks in advance.
