Laura Blackmore gives us some information around custom branding of SharePoint sites and how it can affect the Nintex Workflow designer page.
See section "Reference: Custom master pages and the workflow designer" (2010) and "Style Guide" (2007) of the SDK for further guidance on working with custom branding and Nintex.
