Hi,
PowerBuilder 2022 R3 3397
After a recent Windows 11 (or Edge/WebView2) update, opening an XML file with:
wb_1.Navigate("file:///C:\1.xml")
started showing a red warning banner:
"This site uses XSLT; that functionality is being removed from this browser very soon..."
This began about a week ago.
Has anyone encountered this issue?
Is there an easy way to suppress or disable the warning (registry setting, browser policy, WebView2 option, PowerBuilder update, etc.)?
Thanx.
We have a temporary workaround, but we're looking for a simpler permanent solution.
