Lightbox height and scheduler.xy.margin_top

I have a custom header that is separate from the scheduler div. So right now I am using the scheduler.xy.margin_top = 150; to fix the overflow. However I am running into an issue now with the lightbox running off below the screen. Does anyone know if there is an easy one line solution to this, or do I have to use frames?

Much Thanks

For now (until a more eloquent fix/less ugly), I added override of .dhx_cal_light style:
top:10px!important;

Hello,

Lightbox position will be calculated differently (it always will be displayed in the center of the current view area) in the upcoming version.

Best regards,
Ilya
