Using DIMGROB in program fails while Spreadsheet APP is active

[Marek Russ]

Hello,
I try to write program to draw some custom chart from data within Spreadsheet.
When I use DIMGROB_P(G2, ....
The PRIME dont recognize G2 as graphics variable, but as value of cell g2 :-(
Program ends with "Error: Invalid input"

The simple reproduction of this bug (on emulator too):
1.activate Spreadsheet APP
2.in HOME type G2 [Enter]
return is 0 //or any other value stored in g2 cell

2.activate Statistics 1Var APP
2.in HOME type G2 [Enter]
return is G2

Please is some workaround there for this, until it will be fixed in new firmware?
Thanks!
