JFrame not responding to the MouseEvents

Question

hi,
In my application Jframe which has a menuBar,this menu consists of various radiobuttons options .Intially when a frame opens it has an same square at a specific position .when one of the options in the mebar is clicked it responds accordingly by placing this square in different position and varing the size& the % of expanding.
The following problems i'am facing
1.The MenuBar is visible on the Jframe ,but when we move towards the extreme left corner and click the option will be visible.i'am able to figure it out y this happening
2.The MouseEvents are not recognised,only radio buttons named 1& 3 when selected responds to the Itemlistener whereas the others don't.
plz let me know where am i making mistakes.Plz i have totally ran out of ideas.i'am sending the code for ur clear understanding.
Thanks in advance
your help would be apprecriated

What would cause this?You've got a bug. What it is is anybody's guess.
Your best bet here is to show us your code. We don't want to see all of it, but rather you should condense your code into the smallest bit that still compiles, has no extra code that's not relevant to your problem, but still demonstrates your problem, in other words, an SSCCE (Short, Self Contained, Correct (Compilable), Example). For more info on SSCCEs please look here:
[http://homepage1.nifty.com/algafield/sscce.html|http://homepage1.nifty.com/algafield/sscce.html]
Again, if the code is compilable and runnable more people will be able to help you.
