Touch stylus is single click only (no click and hold feature)

[jacoblapenna]

Description

Stylus touch input registers the initial touch/click but does not recognize continuous drag for drawing. Mouse input works perfectly.

Steps to Reproduce

1. Connect a touchscreen portable monitor (ViewSonic TD1655 with capacitive stylus)
2. Launch DrawPen on Windows
3. Use stylus to touch screen - initial touch registers
4. Try to drag stylus across screen to draw - drag is not recognized
5. Switch to mouse - drag works perfectly

Expected Behavior

Stylus should draw continuous lines when dragging across the screen, similar to mouse behavior.

Actual Behavior

• Initial stylus touch: ✅ Works (registers as click)
• Stylus drag: ❌ Does not work (no continuous drawing)
• Mouse drag: ✅ Works perfectly

Additional Context

• The stylus drag works correctly in other Windows applications (MS Paint, OneNote, Windows Whiteboard)
• The monitor's touch functionality works for clicking/tapping throughout Windows
• This appears to be specifically a touch drag event recognition issue in DrawPen
• The ViewSonic TD1655 uses standard Windows touch protocols (10-point capacitive touch)

Environment

Operating System:

• OS Name: Microsoft Windows 11 Pro
• OS Version: 10.0.26100 Build 26100

DrawPen Version:
v0.0.34 (installed via Windows installer). I don't see where I can actually see the version, but I downloaded and installed only an hour ago and the repo states v0.0.34 as of 4 days ago.

Hardware:

• Primary Display: Latitude 5550
• Secondary Display: ViewSonic TD1655 (15.6" USB-C portable touchscreen monitor)
• Input Device: ViewSonic TD1655 capacitive touchscreen with included passive stylus
• Stylus: ViewSonic passive capacitive stylus (included with TD1655)

Installation Method:
Windows icon on the home page the subsequent DrawPen.Setup.exe downloaded setup file.

Workaround

Currently using mouse input instead of stylus.
