subpanel-scheduling doesn't show hightlight

[rogerliang]

Hi all, the scheduling sub-panel under calls seems not working properly for me.
If scheduling a call for 2007, the scheduling sub panel shows the highlight of time slots have been scheduled for the day correctly, but it comes to 2008, it doesn't show the highlight at all. Does anyone encountered this problem or have any idea what's causing it? Thanks a lot.

My sugarcrm version: 4.5.0f

hi all, I just discovered that the scheduling sub panel in 'schedule calls' is working properly but it has a very small window of showing future activities scheduled. Only within next 3 months activities will be shown on that sub panel, if you are scheduling anything out of that window, it won't tell you if there is a time conflict.

Does anyone know where to change the variable that limits the time-window?
Thanks a lot!
