What sort of graphics card have you got? (and which
drivers/kernel)
lshw gives *-display description: VGA compatible controller product: G71 [GeForce 7300 GS] vendor: nVidia Corporation physical id: 0 bus info: pci@0000:01:00.0 version: a1 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress vga_controller bus_master cap_list rom configuration: driver=nouveau latency=0 resources: irq:16 memory:e1000000-e1ffffff memory:d0000000-dfffffff memory:e0000000-e0ffffff lspci give 01:00.0 VGA compatible controller: nVidia Corporation G71 [GeForce 7300 GS] (rev a1) If I have this right the install put on X.Org X server -- Nouveau display driver (experimental) 1:0.0.16+git20110411+8378443-1+b1 Thought the drive might be a problem so tired installing nvidia-kernel-common 20110515+1 Now I am not positive this was the right thing, and I have no idea how to check to see which one is in use, which might help to see if it is the right one, as the other one is still there! There are a plethora of nvidia things I could install, including nvidia-settings and nvidia-xconfig, butnot found much of use on the internet about what does what I notice that nvidia-kernel-common 20110515+2 is available, but I have not played with forcing yet, and the graphics driver seems a poor one to start with. Can you save the info from the Aven 'about' window -
that can be helpful.

This is going to be difficult to debug remotely if I can't reproduce.
Time for a remote control program that works across the web, been looking for one that works on linux, easy to do on Windows nowadays :(
There should be some wxgtk samples/demos you can run which would show if it is a wx problem or a loch problem. (loch uses VTK, which uses WX).
A bit more of a pointer could be useful, but I will see what I can find
Another thing to try is strace loch<filename> 2>&1> therion.strace.log
strace not found? : fixed that You meant strace -o therion.strace.log loch the command you cave me just dumped it on the screen and made an empty file. (So I resorted to the manual!) Also found xtrace, which might be useful, but the manual did not mean much to me, but was about display outputs, it did complain that I did not specify a display, but at least gave the out the file Available from http://www.ubss.org.uk/__therion/
There is also therion 5.3.8 in unstable. Add that repo and you should be able to do aptitude install therion/unstable
and try that one. It's very unlikely to be different in the graphics area though.
