Problems opening closing forms

I'm making this open source jeoypardy app but i have severe problems
with opening/closing forms. When I close forms they sometimes reappear when I start a new game or some text boxes lag behind and appear after a form is closed. How do I delete/destroy a form from an app and open it agian.. ( i guess this isn't done by show/hode.
Source code is submitted. Please help I've had this problem for two years and unless I can't slove it the app won't be relased.
Just press the butons "fortsatt", "svar" and buttons "100" through "1000" all the way through and press the button "starta spelet" to start/restart the game.

Removed attachment will fix errors in basic4ppc 6.50 before reposting
To my excuse though i usally use basic4ppc 4.0

Your program as posted will not run due to missing/extra parentheses and at least one missing control. Perhaps you should make sure that it will run and then repost it.

Updated zip file

I've update the files and the program now runs..
Now you can help me

Your program still doesn't run in version 6.50.
The following lines are wrong:
50: Sub (cmdFragSvar_Click
1002: Sub )cmdRetMainMenu2_Click

Additionally there are some lines with an odd number of parenthesis.
