Thanks for the prompt response.
I've had a quick look at the SL schedule demo of the tool tip and that is looks good..
With regards to the Ajax Tool Tip control, the functionality that would be useful are the animated "Callout" type boxes and would be really useful in a system where there is a requirement for alot of user input.
For example - when a user tabs from one field to the next a Callout box appears to the right of the field that explians what is required (abit like online assistance) in the input field.
Not sure if this is already part of the SL Tool Tip functionality, but if it is please could you give me some pointers in the right direction.
Thanks in advance
