When using code assist, it gives a Stack Overflow error and Toad closes. (4225539)

When using code assist, Toad gives a Stack Overflow error and this leads to Toad completely shutting down abruptly.

Type something like:

select max(length(a.ACODE) + length(A.
from some_tbl a

When first typing in select max(length(a. Toad gives the parameter hints pop up and the column pop up at the same time. This seem to be a conflict.

Choose the column needed from the column drop down and continue

...select max(length(a.some_col)+ length(a.... but this time a blank outline of the parameter hints pop up displays (just the frame, no info or color), and no column pop up displays at all. Toad hangs for a second, then gives the Stack Overflow error

Error occurred
The application has encountered a problem. We are sorry for the inconvenience.
Stack overflow

Clicks OK to this error and Toad completely closes out.

Code assist popup menu conflict and causes Toad to shut down.

WORKAROUND:
Disable one of the display options

1. Go to View | Options | Editor | Code Assist.
2. Disable the option to Display parameter hints after typing open parenthesis or the option to Display pick list after typing object name followed by a period.

Apply the changes and open a new editor window for these changes to take affect.
