Weird issue printing from Lotus Notes (with resolution)

Got a weird one at work today…

User was reporting that when they tried to print certain mail messages in Lotus Notes (on Windows), the client would close or crash. After upgrading the client and reinstalling the client, I finally got some support files over to IBM.

They came back with what seems to be a simple fix:
Add BrowserRenderPrintNotes=1 to the user’s NOTES.INI file

This tells Notes to use the Notes print dialog box for messages instead of passing off the print dialog to the browser. It seems to happen with messages that includes MIME/HTML. I found a reference to it here: IBM Technote – Windows Print dialog opens instead of Notes Print dialog when trying to print external message (Technote #1291150).

This seems to be working fine so far. Not sure why it just started happening…
