I’m running into a quirky problem where the dhtmlXScheduler control is rendering slightly larger then its div, but when it re-renders by resizing the browser or clicking any of the day\week\month view buttons, the dhtmlXScheduler displays properly. While I get the issue consistently with Firefox, IE8 doesn’t seem affected.
The basic idea is this:
For example, dhx_cal_navline will be created with a width of 839px and then drop down to 822px which is the initial size of myScheduler.
