DW 2021 takes over 1 minute to start, then throws an error ...

[paulc89302236]

DW has started (again) to slow start and crash.

Right now im getting an error "a script in the file "UNKNOWN" has been running for a long time.

Do you want to continue?"

Click no and it dissapears. The home dashboard then presents recent files, however clicking anywhere in that space creates a windows sound alert and nothing selects - theres no interaction in that area.

If i select a particular .php file in my site DW throws alert "encountered a sharing violation while accessing 'path name/file'.

maybe the very slow start is linked ?

How do i resolve this sharing violation? so that i can continue using DW?

Which operating system?

This could be a site cache problem.  

• Is your local site folder defined in DW?  Site > Manage Sites...
• Does your site folder reside on your primary hard drive, not a networked or cloud drive?
• How many assets (files) does your site contain?

If Restoring Preferences doesn't solve the problem, consider creating a new site defenition from Site > New Site and delete the old site definition.
