Issue Details

I am using a touch screen monitor as a user interface and I have an application which uses an event structure. I want the events to be activated on a mouse down action. The mouse down event works as expected when I use a physical mouse, however when I press the same control (button) on the touch panel with my finger the mouse down event is only generated when I release my finger from the screen. Mouse up event works as expected with and without a physical mouse. I am using non NI touchscreen.

Solution

Sometimes the third party touchscreen driver does not register as a pointing device and hence cannot work as a mouse. Some manufacturers have their own specific drivers which can change the behaviour of the touch panel. Please contact the software manufacturer of the third party touch panel to get the drivers.

Additional Information

This issue has been submitted to the ideas exchange as a new 'touch' event, and there are a couple of workarounds listed in the comments. Here is one of them:
a. Go to Windows Start >> Device Manager 
b. Find your touch screen monitor and double click on it 
c. Go to Drivers tab and press Disable - this will disable the drivers. 
d. Reboot the computer
