User Profile Reset: No
Can not confirm with 22.214.171.124 on Windows 10 Home 64-bit en-US (1903)
Also dialog has been reworkd for 6.4.0 alpha1, where we have relaunching the Tip-of-the-day dialog from the Help menu:
The dialog now shows 2, 3, and 4 lines (of 50 characters) for tips the occasional URL link.
Patches for bug 127994 (setting max dialog width to 350px) will land in 6.3.4, due out soon.
With that and changes at 6.4 this IMHO => WFM
Yes, the patch didn't make it into the 6.3 branch (done now) and we got a lot of duplicate issues on this. Thanks for reporting.
