[Tutor] Pyautogui clicking on a modal pop-up dialog

[Jim]

I am using OOSheet and Pyautogui to update a Libreoffice calc sheet.

The following code snippet works until it hits the paste() function.

cols_to_copy = copy_cellrange()
# Copy the columns necessary to calculate the portfolios diversity
colA = S(cols_to_copy[0]).copy()
S('Diversification.R1').paste()
pyautogui.click()

Once I get to paste() it pops up a Libreoffice dialog warning me I am 
pasting into cells that contain data, do I want to paste. The cursor 
sits over the OK button but the click() never runs.

Is there anyway to get Pyautogui to click the button?

Thanks,  Jim
