Problem with interface

[Anonymous]

Hello,
I've recently installed a new version of autocad (2017), chenged interface to classic autocad (done it manually, by turing off ribbon tab and customizing toolbars , and then problem appeard). There is another possibility, that problem appeard after changing startup. Getting to point - when I started working and using pan or scroll drawning space started to shrink and to widen. It isn't a very big problem, but to be honest it make my work very irritaiting. 
I do not know how to define this problem and find it in internet.

Wrong forum.  This is the Dynamic Blocks forum.  Your issue has nothing at all to do with dynamic blocks.
