cwppr0033E error when installing a plugin

Today when installing the SMARTNSF plugin in my DDE (9.0.1FP9 SH123) I got the following error message:

install_error

I wish I could tell you the solution for it, but I can’t.

I tried several approaches (directly install via remote location, update site with signed documents).

I tried it with another plugin, same error message.

Google was also not my friend. Perhaps you are?

Buggy LotusScript debugger – Looses focus at startup.

Whenever I start the LotusScript debugger it comes up and then disappears. It simply loses focus.  I cannot set focus on the debugger via the tab controls under Windows. What is worst, Domino Designer also becomes frozen, since it is said to the background by the debugger.

Have more people experienced this pain and how did you solved it? Can it be resolved by any of the preferences in Designer under debug?

I read a similar case here. I have registered a support case at IBM so I am waiting for a reply. But in the mean time I cannot test my code…
