I reference to your questions :
We suggest you make the following changes in the rotator's setup in order to avoid the first issue :
- you need to specify two additional parameters in the RadRotator's declaration - ItemWidth and ItemHeight, according to the size of the showed items
- the RadRotator control does not support values in percent and you need to use fixed values in its declaration
- we recommend you use the "1" instead of "0" as a value of the FrameDuration property. The value is in millisecond and the behavior of the control will be the same.
In reference to the second issue :
We are aware with that behavior under IE. This is a browser specific behavior and fortunately this
workaround works and you can use it in order to avoid the issue.
