[Eric] slow problem saving file 4.2.0

[Linos]

Hello,
	i am using the new released eric4 version 4.2.0 (r2385), i like this versions, the 
graphics are clearly more beautiful than before and i think the highlight of current text 
and the better rope integration are great new features, i only have a problem when i try 
to save the changes to my script (2432 lines) i have to wait with the application freezed 
about 3~4 seconds, i had not this problem with old 4.1 version, can i fix this problem in 
any way? I have other question, in the project homepage in donate link i read this message 
about donations:

Donations will be used to buy the required commercial licenses of Qt and PyQt for Windows. 
This will enhance the support of this OS.

Well i am using eric4 ever in linux so i dont have an special interest on make it better 
in windows, i would like to support the develop of the ide that i am using to my projects 
without attach my donation to an specific platform, i suppose i should use the same link, 
no? Thanks in advance.

Regards,
Miguel Angel.
