Crash when exporting data (Linux) - Index was outside the bounds of the array.

[Oliv4945]

Hello,

I am using v2.0.1.0 under Linux, the capture and save are fine, but exporting the data results in an application crash with the following log:

Unhandled exception. System.IndexOutOfRangeException: Index was outside the bounds of the array.

Hi.

Thanks for the report, I think I have found the problem. Could you please test this build? I don't have a Linux machine at hand to test it. This should correct the problem and disable the transparency (on supported OS's) to improve performance.

linux-x64.zip

Cheers.

Thank you, your fix is working!

In the mean time I wrote a small ".lac" converter in Python to transform my data... It took me more time than I want to admit to find out that the data are saved in decimal :)
