Bug or limitation of maximum appointments ?

[samin]

i implement a schedulerview. when scheduler is in Day,week or timeline mode all thing work true. in this situation my appointments in maximum are 50 apps. 

but when i select month view if appointments are 528 , it shows up them truly but if I increase them to 529 or above ...scheduler hangs for some second and then below windows (attached screenshot ) appears on screen. and after that there is below error in corner of IE.

Hi samin,

Most probably you have an appointment which Start Date is after End Date. This is causing problems with RadScheduleView. We will try to improve the error message in a future release.

If you are sure that appointments are correct (e.g. End date is bigger than Start date) please send us demo project so that we can reproduce this error.
