Force Balloontip To Close After A Few Seconds?

I'd like to show a NotifyIcon BalloonTip to the user and close it after two seconds.No matter what value I enter there it never closes, unless I keep moving the mouse and then it always closes after exactly 10 seconds. After doing a Google search I found this page.Here are two quotes from that page.

Quote:

The BallonTip timeout is only respected if the shell detects the "user presence" (i.e. mouse moves or keyboard input). If none of these happen (because you are watching the bubble) it will sit there indefinately. The logic behind this design being that users should not miss notifications when they are away from their machines. This is the "By Design" shell behavior.

Minimum and maximum timeout values are enforced by the operating system and are typically 10 and 30 seconds, respectively, however this can vary depending on the operating system. If you declare timeout value as less than minimum, the real timeout will be minimum; while the value more than maximum will be changed into maximum value. So timeout values that are too large or too small are adjusted to the appropriate minimum or maximum value.is there any way to force it to close after two seconds? My BalloonTips are shown based on the action of the user and not during some background process, so 10 seconds is way too long.
