i wish they would change "Error: unable to create more that one texture window" to more than. i also wish i knew what it meant, especially in a scene with no textures..
What do you do to get this error?
Nothing! just does it on opening a saved scene sometimes and doesn't do it on the same scene all the time, or even on different machines, it just pops up every now and again, even in a scene saved in wireframe mode..
I guess you could try importing your scene into a new scene file or exporting the essentials from your scene and then opening what you exported and see if that resolves the issue.
