Description gossi

2011-10-08 10:18:56 EDT

Build Identifier: 3.0.0.v20110516-1100-77--84_23JBVgSVXO7XGJz0VLa9O

When switching tabs in the editor, the cursor changes from normal mouse cursor to busy mouse cursor. The change is very fast, so it happens 3-5 times during the switch. Overall the switch takes approximately 1 second to finish. Looks like some heavy operations are done in the background, giving an overall very uncomfortable feeling. The delay makes it also very unresponsive.

Reproducible: Always

Steps to Reproduce:
1. Open multiple Tabs
2. Switch between them with the mouse

Now I don't detect the cursor changes to busy mouse cursor, at least it is no longer visible, but switching between php and php/txt files tabs takes a second (0.8 - 0.9 sec on Win 7 and 1.0 - 1.1 sec on Mac) and the heavy feeling is still experienced.

Machines under test:

Win 7, 64 bit:
RAM: 2 GB
CPU: 4 GHz (Core i5)

Mac Mountain Lion:
RAM: 4 GB
CPU: 2.5 GHz (Core i5)
