Dear Chimera development team, I have a little problem when I use Chimera with my new Video card Nvidia geforce GT 430. Chimera runs well the firsts 2 minutes but, then, it gets stucked and I can't move whatever I had open in these moment (even if I had a little model of less than 50 atoms!). I've been updated the drivers of the video card twice and also I re-installed the operating System but Chimera remains getting stucked. Before change the Video Card (first I had a ATI Radeon (I don't remember the model) of 1GB) Chimera runs perfectly. Anyone has any idea of how can I fix it without change the video card? (the best solution is using back the ATI video card... but I want to use NVidia in my computer) I'm running Chimera over Linux (Opensuse 11.0 32 bits and Opensuse 12.1 64 bits) in a Intel Dual core CPU E8400 @ 3.00 GHz with 2 GB of RAM. Thank you in advance. Elisabeth Ortega-Carrasco Ph.D. Student. Universitat Autònoma de Barcelona (Spain)
