Inkpicture drawing is invisible on Userform Control

[ConorN]

So I have a workbook that records sign ins and sing outs of clients via a userform. When they come in they fill in some details on the userform, that's logged on the next available row in a worksheet.
When they leave they fill in some more details and when done another userform pops up with an InkPicture control, in which they sign their name (using a stylus or finger on touch screen). The control save the image, resizes it and adds it into the row recording their data.

For some reason while they are signing, nothing shows in the Inkpicture control. The image saved from it saves just fine, so it is recording the brush strokes, but nothing is visibly happening on screen while they write.
I have zero idea why.
the image attached shows the issue, the control is blank (Signature invisible), but the image file has been successfully created and saved to the worksheet.

Ok, no idea why it was happening. But deleting the InkPicture control from the userform and re adding it fixed the issue.

I only just saw your query now, and had just finished trying testing it out on my computer, only to discover that you yet again beat me to the punchline - I really should read these things through to the end.

So I have no idea why either - I was going to ask if you experienced the same problem if you were to start a new userform and add a new InkPicture control, but you beat me to it.... For completeness, I checked the following properties:

• AutoRedraw - True / False
• Collection Mode - Ink / Gesture / Ink & Gesture
• Dynamic Rendering - True / False
• Enabled - obviously not that
• InkEnabled - not that either

Nothing seemed to cause a similar problem to the one you outlined.

The only thing I could think of is maybe the ink is set to white, but I suspect you'd be able to tell from the picture. Other than that, perhaps some misconfigured code?
Sorry. I'd be interested to know what the problem was if you ever find out.
