## WPF Touch Stops Working After Rapid/Prolonged Use Of Popups
|
|
|
|
### Symptoms
|
|
On a touch or stylus-enabled machine, WPF applications may see a loss of touch or stylus after rapid or prolonged use of popups (e.g. ComboBoxes, DropDown Menus).
|
|
|
|
### Cause
|
|
A change to disposal of HwndSource in .NET 4.7 caused Popups to not correctly cleanup touch resources. This eventually can lead to loss of touch/stylus interaction.
|
|
|
|
### Resolution
|
|
The fix for this is expected in future servicing update for Windows 10.
