When right-clicking on a document (or a selection of documents) in the Documents tool view, a contextual menu normally pops up instantaneously. This is certainly the case when the Perforce plugin is disabled.

If the Perforce plugin is enabled, when right-clicking on a single document, there is a brief delay (about 2 seconds) before the contextual menu appears. When selecting n documents and right-clicking on the selection, the delay increases by about n times (e.g. right clicking on five selected documents requires about 10 seconds before the contextual menu appears). This is problematic if, for example, I want to select multiple documents to close from the contextual menu.
