opening the excel working file -> opens an additional one with empty contents - how get rid of 2nd ws

[driller]

at the beginning with an excel working file only 1 workbook (wb1)opened.

after filling wb1 with data from websites (webscraping) writing vba excel macros for analysis those data.
After an excel crash (guess bad scripting) suddenly a 2nd workbook (wb2) opens (which is empty) now on each time wb1 will be started.
I cant get rid of wb2.

My question is, how can I find where is the 2ns wb get started....thanks for suggestions. If more Information is required pls ask for. Thank you

...found additional behaviour while closing excel wb1.

procedures 1:
1. opening wb1:--> wb1 opens & wb2 opens
2. closing wb1: --> wb1 closed
3. closing wb2 (empty wb) : --> wb2 closed

procedure 2:
1. opening wb1:--> wb1 opens & wb2 opens (-->same behaviour)
2. closing wb1:--> wb1 closed & wb2 still open
3. opening wb1: --> wb1 opens and wb2 will be closed ( different behaviour)

procedure 3:
1. closing wb1: --> wb1 closed & wb2 is not open
'----------------------------
2. opening wb1: --> wb1 opening & wb2 opening
----------------------------
my questions:
-any idea how to get out of this loop?
- where to start to find this "link" --> guess - must be stored somewhere with command open file
( habe not writen or tried script to open file via FSO functions)

where is this "command" located that produces this behaviour ?
how can i erase this "link" ? in registry ??
