I made it bigger 2 times.
It took about 7 minutes of waiting for the response of my computer. While doing this, I got: 2x "Process not responding" windows; 99% of used RAM; 1x Freeze; Many disk activity... ...1x Blackscreen; And totally frozen Chrome for 7 minutes! PS. If you try to open it, it will froze for a long time. #Checked-With-8GB-Of-RAM-And-A-Powerful-3.6GHz-Processor
