== Symptom ==
run TaskCoach => "task window" shows nothing
* click new task button => New task window (Task properties) will not pop-up
== Findings ==
* Versions after 1.3.17 also HAVE such problem
Versions before 1.3.16 did NOT have such problem
replace library.zip\taskcoachlib\render.pyo in 1.3.17 (or 1.3.18) with that from 1.3.16 can "work around" the problem.
=> it looks the problem comes from render.py since 1.3.17
