DWC spinning wheen not stopping when macro completes.

I often want to get user input in a macro. Currently, the only way I know how is to use an M291 command with a message like " select OK for 1 and Cancel for 2. I'm setting this up in the generic callable macro below.

; Macro to be called from other macros to let user select one of two options (OK and Cancel)
; Parameters 
;     S =  Message to be displayed
; Return 
;   Global.OK_CANCEL is set to "OK" or "CANCEL"

; Usage  M98 P"<dir>/OK_Cancel_checker.g" S"Select OK for <option 1> and Cancel for <option 2>"

if !exists(global.OK_CANCEL)
  global OK_CANCEL = "NO MESSAGE"
else
  set global.OK_CANCEL = "NO MESSAGE"

;Check for parameters

if !exists(param.S)  ; see if a parameter was provided
  M291 P"Message parameter not provided. "  S0 T5   
  M99
  
  
set global.OK_CANCEL = "CANCEL"
M291 P{param.S} S3 T-1
set global.OK_CANCEL = "OK"
M99

When I call this with the following command in the command page in DWC, then select OK, the global variable is set and the macro exits as expected. However, if I select Cancel, the global variable is set, but the little spinning "busy" wheel over the send button in DWC keeps spinning. I can send a command from the Send box at the top of DWC and it executes and stops the "busy" wheel.

M98 P"0:/macros/3. debug_stuff/OK_Cancel_checker.g" S"select OK for OK and Cancel for cancel"

If I embed this command in another macro and run that (which is normal usage, then select Cancel, the "busy" wheel does not keep spinning.

I'm running RRF 3.4.0 and DWC 3.4.0
