Thread: On Pressing JButton, JAVA Crashes'

I have created a project in Netbeans using swing components...'
Multiple frames are displayed one after another as the project runs...'
'
But most frequently, somewhere in the middle, when I press 'ok'(JButton), the project is closed with giving error information as JAVA crashed'
It happens most of the times, but sometimes, JButton works correctly showing next frame and the project runs successfully...'
'
Please if any1 could help me for how to prevent JAVA from crashing...'
The message displayed in Netbeans Console is:

# # An unexpected error has been detected by Java Runtime Environment: # # EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x7625a86c, pid=1980, tid=3724 # # Java VM: Java HotSpot(TM) Client VM (1.7.0-ea-b19 mixed mode, sharing windows-x86) # Problematic frame: # C [SHLWAPI.dll+0x1a86c] # # An error report file with more information is saved as: # H:\Editions\pillu\Image_Scrambler\hs_err_pid1980.log # # If you would like to submit a bug report, please visit: # http://java.sun.com/webapps/bugreport/crash.jsp # The crash happened outside the Java Virtual Machine in native code. # See problematic frame for where to report the bug. # Java Result: 1 BUILD SUCCESSFUL (total time: 24 seconds)

'
I use
OS: Windows 7'
IDE: Netbeans 7.0.1'
JAVA: Version 1.7'
Also, I assigned VM memory as -Xmx512m to deal with larger files in project...'
'
Thanx in advance...'

Well, what did it say?

@jps...sorry for not posting the contents of log file...'
