open drawing takes 2 long

[frunza_samuel]

i have problem with one of my drawings. i created a solid, and most operations with it reaquire some time, not 1-2 seconds like it used to . When i try to open the file it gets stuck about 1min at 99% when it says loading modeler's DDLs.
I tryed some more operations with that solid, like mirror, and others and saved the drawing again, but the oppening time grows dramatically and i't might never open again.... Is this normal? Is there any way to reduce that regeneration process, or any adwice..?
Thx for your help

We just found this (actually our reseller found it for us). Drawings were taking 1-2 minutes to open, due to xrefs and multiple annotation scales.
Drawings are much faster now.

There are actually 3 3D solid objects in there.
They're all pretty large as well. Maybe seperating them would help your lag time.
Also, just waiting will allow the drawing to open.
