Workfusion studio hangs when coding in code perspective

I am using Workfusion Studio pro version and doing excel manipulation using apache poi.
My problem is when I am coding the studio is hanging for every letter i type and it is very frustrating. I am forced to write my code in notepad and then copy the code into the studio.

I am currently developing in client PC. Its Specifications are followed:
processor: intel Xenon
RAM: 32
OS: Windows 7
type: 64 bit

Can anyone help me?

Thank you

Hi @mjana what version of the tool are you using?
We used to have this issue, but it was fixed in version 2.3

@mjana if you have a newer version, check the preferences in WorkFusion Studio - Content Assistant. It has to be disabled.
