WL seems to crash when I click WL "more info" hyperlink in fundamental data....screenshot attached

First things first, this is not a crash. It's an unhandled exception dialog which you can close and continue working with Wealth-Lab - unlike a crash which forcibly closes application. I've edited the topic title which could be misleading.

Could you click on "Details" and copy/paste the error message when replying, please?

P.S. Hint: You should really stick with PNG as JPG is truly suboptimal for screenshots. If you haven't seen this famous comics, it's perfect time :)

JPEG or PNG – Which Image Format Offers Better Quality?

thanks please see below

See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

Thanks for reporting the issue, I will pass it on to the development team.

Update:

64-bit WLP (only) has some trouble opening the manual (a PDF file) at:
C:\Program Files\Fidelity Investments\Wealth-Lab Pro/WLP Fundamental Data Guide.pdf

As a workaround, navigate there using Windows Explorer (or your file manager of choice) and open it directly.

Hmm it seems that it's been there for 5 years: Cannot Access Fundamental Data Guide

To be fixed in a future build of WLP.
