How To Prevent OWASP ZAP & W3AF GUI From Freezing & Hanging In Kali Linux 2.0 32Bit?

Hi

I am new here and I don't know if this is the right section to post this question.

Feel free to move it to the right section of this forum.

I have Kali Linux 2.0 32bit Inbuilt Vmware Custom Images running on Vmware Workstation 12 Pro 64bit and my local host is Windows 7 Enterprise 64 bit on HP 2000 notebook pc.

Owasp Zap GUI, W3AF GUI and other applications GUI in my Kali Linux 2.0 32bit on Vmware Workstation 12 Pro freezes whenever I am scanning website with these applications.

I want Owasp Zap GUI, W3AF GUI and other applications GUI to stop freezing and hanging in my Kali Linux 2.0 32bit Inbuilt Vmware Custom Images running on Vmware Workstation 12 Pro 64bit and my local host is Windows 7 Enterprise 64 bit on HP 2000 notebook pc.

Don't be angry by my question, I need answers!

Thanks
