Hi Esenthel,
yesterday I'd make a update of my Mac OS X system from Mountain Lion to Mavericks. Is there a issue you knew about during starting Esenthel? Today I have to start the egine three times, before Esenthel is running. I've got the error report attached as a file.

Hi!
Thanks for reporting the error, this is definitely a bug in the OS, but I have an idea about a workaround, I'll make it for the next release. Glad that it starts after a few attempts though

Also, if you preview the Settings.txt
what's your screen resolution?
<Video
ScreenX="1920"
ScreenY="1110"
Can you try settings values that are multiple of 16?
For example 1024x512 just to test

Thank you for your support!
Yes I'm also glad, that the engine starts whatever the bug is. Ok, I had set the preview settings to 1024 x 512 , a power of 16 and t Esenthel starts at once .
Thank you for your help!
