Each time I attempt to open the OpenScript Editor the following error occurs:
Not enough memory. Close other applications or save this
book and try again.
After clicking on the OK button to dismiss the error, the Script window does open, and the editor works fine, but the Toolbar buttons seem to be missing.
The error message is the result ToolBook failing to be able to render the button images in the Toolbar.
Interestingly, although you can't see the buttons, they still work if you click in the right button locations. In fact if you move your mouse over the missing button locations, you will see pop-up tooltips telling you what that button does.
Although you can't see the buttons of the Toolbar, you can use the menus instead, because each Toolbar button has a cooresponding entry in one of the various menus.
This problem started on February 11, 2020, with the release of the KB4532693 Windows Update. That update will identify itself as:
2020-02 Cumulative Update for Windows 10 Version 1909 [or 1903]
for x64-based Systems (KB4532693)
Unfortunately Microsoft broke something within this update, which is negatively affecting all versions of ToolBook (and very likely other software on the market). If you remove this update, the problem will go away. Please work with your IT Department to determine if you can/should remove this update.
We are hopeful that Microsoft will fix this underlying problem in a future Windows update, in which case the problem would just disappear.
