Open Dental Forum

Open Dental won't open at all with Mono 1.2.6, I get the following error:
Unhandled Exception: System.ArgumentOutOfRangeException: Argument is out of range.
Parameter name: startIndex
at System.String.Substring (Int32 startIndex) [0x00000]

Seems to be a display problem. Have tried OD 4.8 and OD 5.1 by copying the application folder to the Linux machine. Tried installing the libgdiplus package and no luck. I hope someone has seen this or has an idea of what the cause or fix might be.

Right. Linux client support has been broken for a few months. We've put a lot of work into it recently, and now with version 5.5, it will at least load, but it's buggy. We will be updating the Linux page with info about the specific version of Mono required. I recognize the specific error message you are getting as one that was already fixed for version 5.5.
