Local variables in other event sheets can create naming conflicts with global variables.
Construct 80.2 (32-bit)
Windows XP SP3
1. Create EventSheet1
2. Create Group Group1
3. Create any subevent
3. Add local variable var1 to Group1
4. Create EventSheet2
5. Create global variable Var1
The name 'var1' is already used in this scope.
I wouldn't imagine local vars and global vars are supposed to conflict since they have different scopes.
