Problem debugging in wxquincy

[RallyTronics]

I am working in Win 10. When I try to debug some of the example scripts ( i.e. sieve.p ) using F5 in quincy I get a popup error:

Couldn't retrieve information about list control item 0.

If I click the run button CTRL+F5 scripts run as expected.

I am building with Debug info set to Symbolic debugging and instruction set at Full

Is there a setting/option I am missing to make this work?
